In here, we explain process steps of vacuum molding and advantages and disadvantages of vacuum molding below. Large dimensional hollow parts. For certain types of liquid vinyls, the term slush molding is also used. During the cooling process, the Polymer solidifies the required shape and then gradually contracts before the operator eventually removes it from the mold. Benefits or Advantages of Job Rotation in HRM: The following mentioned are few benefits of job rotation process in organizations. Depending on the plastic that’s used, rotomolded products can be either more rigid or more flexible. Copyright © 2019 Gemini Group, Inc. All Rights Reserved.
